Theory: Markets and the tyranny of the majority; Are "lumpy" markets a problem?; Empirical evidence: Who benefits whom in practice; Who benefits whom in the neighborhood; Preference minorities as citizens and consumers -- Market solutions and their limits: Market enlargement and consumer...

This paper analyses a model of electoral competition with lobbying, where candidates hold private information about their willingness to pander to lobbies, if elected. I show that this uncertainty induces risk-averse voters to choose candidates who implement policies biased in favor of the...

Utilitarian voting (UV) is defined in this paper as any voting rule that allows the voter to rank all of the alternatives by means of the scores permitted under a given voting scale. Specific UV rules that have been proposed are approval voting, allowing the scores 0, 1; range voting, allowing...

The paper challenges the "orthodox doctrine" of collective choice theory according to which Arrow's "general possibility theorem" precludes rational decision procedures generally and implies that in particular all voting procedures must be flawed. I point out that all voting procedures are...

When based on perceived rather than on objective income distributions, the Meltzer-Richards hypothesis and the POUM hypothesis work quite well empirically: there exists a positive link between perceived inequality or perceived upward mobility and the extent of redistribution in democratic...

We show theoretical and experimental results that demonstrate the potential of transparency to influence committee decision making and deliberation. We present a model in which committee members have career concerns and unanimity is needed to change the status quo. We study three scenarios -...

In Switzerland, two key church institutions the Conference of Swiss Bishops (CSB) and the Federation of Protestant Churches (FPC) make public recommendations on how to vote for certain referenda. We leverage this unique situation to directly measure religious organizations power to shape human...
